Interesting... That is one possibility, though I am not sure why they would pull the old firmware until they have the new firmwre up. Its possible that they might have noticed a bug or something and pulled it until they correct the bug.

Looking at the forums at the ectaco site, it looks like the forum is still on the ftp site. Not sure why they no longer have it on the website... though it might be because the firmware may not be compatible with the new battery powered Jetbook.
